To all .whom t may concern:

the following is a full, clear, andexactde- `scription', suchas-willenable others skilled in the art to4 which it appertains to makeand use the' same, reference beingmad `tothe ac# companying drawings,forming part of this specification, in which--. V

Figure l4 isa side' elevational view, partly insection, of myimproveddraft rigging; Fig. 2 is a top plan view, partly in horizontallsectionyshowingthe draft rigging applied to thel cheek plates of arailway car; and Fig. 3 is a horizontal sectional viewtaken on theline3-3 of Fig. 1.

This invention relates to new and useful.

improvements in .draft riggings for railway cars. v

In the preferred form of inv invention, a

yoke, which embraces or partially embraces springs constituting.theshock-absorbing inediuin of the draft rigging, yis built up ofsections pivotally connected together, one ofv said yoke sections beingsecured-tothe drawbar. This construction allows a portion of 3c, theyoke to swing horizontally on.a pivot,

and the said yoke is thereby relieved ofthe abnormal stresses to whichit is subjected when the car is going around acurve.

My improved .yoke is. particularly adapted for use in connection with atandem spring'` draft rigging, but I'wish it to 'be under-` stood thatthe use of my invention isnot limited to this or any other particularform vof'draft ri ging. 3,

The draft rigging herein shogvvnis of the ordinary tandem type, and iscomposed of `two springs 1, interposed between follower plates 2 and 3.The follower plates normally engage lugs on cheek plates 4,',as shown inmally engagesl the frontv 'follower plate 2.

Fig. 2. 5 indicates the drawbzft'whichnor- Yoke members @are secured tothe drawbar by means, of rivets 7, or other suitable fastening-devices,the forward ends of 'said members being provided with lips 8 which arearranged between lugs 5a and 5b formed integral with the drawbar. Thusthemeinbers 6 may be said to constitute rearward extensions of thedrawbar. The members 6 constitute the front section of va yoke andabsoi'" have curvedr'rear endswhich engage correspondinglyshapedshoulders 9 on. the reary v -yoke section. The rear yoke sectionprefenably'embracesfthe rear draft spring and4 is provided. withan enlargedfront portion l() havin curved faces 11.0%l which normally engage teintermediate follower plates 2 and 3, respectively, The rearvv end 'ofeach nicmber 6 isiprovided with a circular boss l1 'which extends into acircular socket in the rear yoke-section; A bolt or rivet l2, ar-

yoke section. The circular bosses ll forml a `'ranged 'within a 'pieceof' pipe 13,' passes through the center of the bosses lll through theenlarged portion 10 of the rear PVOm1 Connection. between the frontand"` f rear yoke sections and prevent the rivet 12 and pipe 13 fromreceiving a shearingv strain during butling and pulling shocks..

Thesprings 1 are compressed between `the the' drawbar and yoke moveV theollower plates 2 rearwardly and the follower plates 3 are prevented fromlmoving by lugs'on the cheek. plates ll. The pulling shocks on thefollower plates when the car receives a builtu ing or pulling shock.During buiin shocks drawbarcause the yoke to move the follower I plates3 forward and during this movement the follower plates 2 areheld'stationary by lugs on the cheek plates 4.

Having thus described my invention, what I claim as new and vdesire tosecure by Let ters Patent is: lain4 a `draft rigging, @shock-absorbingdevice, a drawbar, and a yoke, said yoke be ling composed of membersthat are pivotally connected together intermediate the ends of Vsaid.shock-absorbing device. i i 2. Ina draft rigging, a, shock-absorbingwmeans comprising a plurality of elements,

and an actuating means coperating with said shocloabsorbing means, saidactuating.iv means comprising members that are pivotjally connectedtogether at a point between the elements of the shoclcabsorbingmeans-,1,

t. In a draft ri O'ino" end followers 'inf ico? eiid and intermediatefollowers, a yoke member, and a drawbar having rearward extensions thatare pivotally connected to said yoke member at a point between two ofthe intermediate followers.

5. In a draft rigging, a drawbar, a yoke composed of sections pivotallyconnected together, one of said yoke. sections heilig secnred to thedrawbar, and a shock-absorbing element actnated by said yoke anddrawbar.

6. in a draft rigging, a drawbai', a yoke composed of a lplurality ofsections, one of which is securedto the drawbar, and a shock-absorbingelement embraced by said yoke.

7. In a draft rigging, a plurality of shockaiisorbing devices, a yokeembracing' said devices and comprising a plurality of sections thatvarepivotally connected together intermediate said devices, and a drawbarconnected to one of said yoke sections.

.8. A tandem draft rigging comprising end followers and intermediatefollowers, shock-absorbing devices arranged 'between' saidfollo\vers,members cooperating with said end followers, and a pivotalconnection between said members located between the intermediatefollowers.

9. In a draft rigging, a drawbar, end followers, intermediate followers,a shock-absorbing device interposed between each end and intermediatefollower', a yoke comprising two sections, one of which entirelysurrounds one of the end and intermediate fol` lowers, theother yokesection beingin the form of bars rigidly connected to the drawbar andpivoted to the first-mentioned yoke section.

10. i yoke for draft rigging, comprising sections pivotally connectedtogether.

11. A yoke for tandem draft riggings,l comprising a rear section havingan integral portion that is adapted 'to lie between the intermediatefollowers of the rigging, and

integral portion.

12. A yoke for tandem draft riggings,

` comprising a rear section having-an integral g portionthat is adaptedto lie between the intermediate followers of the rigging, and a frontsection having integral projections that fit in sockets in the integralportion of said reail section so as to pivotally connect said sectionstogether.

13. AA tandem draft rigging', comprising end followers and intermediatefollowers, a pair of shock-absorbing devices coperating with saidfollowers, a yoke surrounding the rear shock-absorbing device and thefollowers that cooperate therewith, and a drawbar coperating with theend follower of the front shock-absorbing device and having rearwardextensions thatare pivotally connected to said yoke.
